In this paper, a novel event-triggered observer is proposed to decrease the information exchange in continuous-time linear networked systems. The structure of the proposed observer consists of two main parts. The first one, called the event-triggered mechanism (ETM), is placed by the system and is used to determine when the measured output of the system must be sent through the network. The ETM consists of a traditional Luenberger observer, an event-triggered local observer, and an event-detector. The second part is a copy of the event-triggered local observer which is used to estimate the system state using the transmitted data from the sensors. Under the observability assumption, it is proved that the error between the system state and its estimation is asymptotically limited to a predetermined bound. Moreover, it is guaranteed that the Zeno behaviour is avoided. Numerical simulations are provided to demonstrate the design procedure of the proposed event-triggered observer.

在本文中，提出了一种新颖的事件触发观察器来减少连续时间线性网络系统中的信息交换。拟议观察者的结构由两个主要部分组成。第一个称为事件触发机制 (ETM)，由系统放置，用于确定系统的测量输出何时必须通过网络发送。ETM 由一个传统的 Luenberger 观察器、一个事件触发的本地观察器和一个事件检测器组成。第二部分是事件触发的本地观察器的副本，用于使用来自传感器的传输数据来估计系统状态。在可观察性假设下，证明了系统状态与其估计之间的误差渐近地限制在预定的界限内。而且，保证避免 Zeno 行为。提供了数值模拟来演示所提出的事件触发观测器的设计过程。
